Most Lansweeper subscriptions limit the number of assets you can scan. Once you've reached your licensed asset limit, scanning of new and existing assets stops until you delete some assets or upgrade your subscription.
So which machines count towards your limit? Anything listed when you click the Assets link at the top of the web console counts towards your licensed asset limit, except for monitor assets. So any Linux, Unix, Mac and Windows computers, VMware servers, network devices (printers, switches...) and manually created assets count towards your limit, but monitors don't. Monitors are technically assets as well, but they do not count towards your limit.
For a count of all assets in your database, click the Assets link at the top of the web console. For a count of all assets that count towards your licensed asset limit, access the Configuration\Your Lansweeper License section of the web console. In the example below, there are 618 assets in our database, including 192 monitors. As monitors do not count towards our limit, there are 426 licensed assets in our database (618 assets minus 192 monitors) and we can add an additional 74 assets before running into the limit of our Standard subscription, which has 500 assets included.
